<h1>Graphs <img src="images/graphs1.jpg"></h1>


<p>Graphs are <a href="objects.htm">objects</a> that can be used to record, visualize or export data from a <a href="simulation.htm">simulation</a>. They are very powerful and flexible. The user can select from a multitude of data types applied to specific objects to record. Data is recorded as a data stream (sequential list of data values) that can be visualized in three different ways:
</p>

<li><strong>Time graphs</strong>: a time graph of a single data stream (time vs data stream).
</li>

<li><strong>X/Y graphs</strong>: a graph that combines two data streams (data stream A vs data stream B).
</li>

<li><strong>3D curves</strong>: a 3D graph that combines three data streams in time (time vs (data stream A, data stream B, data stream C)).
</li>

<p>
Following figure illustrates the graph functionality:

<p>A graph is added to the scene with [Menu bar --&gt; Add --&gt; Graph]. What you see is the three dimensional representation of the graph. If a 3D curve was defined for that graph, that curve is directly visible as can be seen in following figure:<br>

<p>Data streams recorded by a graph can be exported to a *.csv file (Comma Separated Values) that can easily be imported by various applications (e.g. Excel). In the <a href="scenes.htm">scene</a>, select the graphs you want to export the data from, and select [Menu bar --&gt; File --&gt; Export --&gt; Selected graphs as CSV...]. The unit of exported data streams will be in meters, kilograms, seconds and degrees (or a combination of those). <br>
